Class Log4jConfigServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.springframework.web.util.Log4jConfigServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class Log4jConfigServlet

extends javax.servlet.http.HttpServlet

Bootstrap servlet for custom Log4J initialization in a web environment. Simply delegates to Log4jWebConfigurer.

Note: This servlet should have a lower load-on-startup value in web.xml than ContextLoaderServlet, when using custom Log4J initialization.

Note that this class has been deprecated for containers implementing Servlet API 2.4 or higher in favour of Log4jConfigListener.
According to Servlet 2.4, listeners must be initialized before load-on-startup servlets. Many Servlet 2.3 containers already enforce this behaviour (see ContextLoaderServlet javadoc for details). If you use such a container, this servlet can be replaced with Log4jConfigListener. Else or if working with a Servlet 2.2 container, stick with this servlet.

public void destroy()

doService

public void doService(javax.servlet.http.HttpServletRequest request,
                      javax.servlet.http.HttpServletResponse response)
               throws java.io.IOException

This should never even be called since no mapping to this servlet should ever be created in web.xml. That's why a correctly invoked Servlet 2.3 listener is much more appropriate for initialization work ;-)

Throws:

java.io.IOException

getServletInfo

public java.lang.String getServletInfo()
